Default where is the ecu rpm signal wire for an sti?

i need to locate the ecu rpm signal wire for my turbosmart e-boost2. the turbosmart instructions have a schematic for the pins but i have a feeling it is for the british version of the sti since it doesn't correlate. thanks.

thanks for the help, hap. we asked phil (grabow) and he indicated that there have been problems when the e-b2 connection was made to anything other than the ecu rpm signal wire. i just received the sti wiring diagram so that should clarify the location. if you've had no problems with your location, we might give that a try.

from what i can tell, the same signal that goes into the ecu, just comes out of the ecu unchanged...and then goes to the gauge cluster.

A=B134
B=B135
and so on....

The "little squares" graphics let you know how to read the pin coordinates.
